HY-Phaser is a phaser effect.
Some of parameters can be modulated by envelope follower.
Depth = modulation depth
Rate = modulation speed
FB = feedback
Width = shifting phase of left LFO.
HP = cutoff frequency of highpass filter
LP = cutoff frequency of lowpass filter.
Dry = level of dry signal
Wet = level of wet signal.
MenuBox = waveform
Smooth = smoothing LFO output.
depth, rate and mix parameter can be modulate by envelope follower.
Slider = adjusts depth of env follower to the parameter (-100 to 100%).
